Guide on Polluted Urban Rivers Control in China

About 80 percent of rivers in urban regions in China have been found to be filthy

In its effort to clean up polluted urban rivers, China will give more weight to public opinion in determining which rivers are given a clean bill of health and removed from a listing of polluted waters.

At least 60 percent of respondents to a government survey must conclude that a river or pond is polluted to have it included in the list of rivers that are polluted and to be remedied.
